Application filed June 2, 1916. Serial No. 101,304.

To all whom t may concern;

Be it known that I, PUnoY FORBES, a citizen of the United States of America, residing at Lakewood, in the countyv of Oconto and State of Wisconsin, have invented cerl tain new and useful Improvements in Rail- Joints, of-which the following 1s a specification, reference being had therein to the accompanying drawing.

Msists therein to provide a rail joint free of n The invention relates to rail joints, whereby abutting rails of a track may be interconnected in an eiiicient and simple manner. The principal object of the lnvention conbolts, which may be readily assembled or l talninl apart.

""lfurther object of the invention` consistsi in providing a rail joint which simultaiieou'sly acts in the capacity of an antier; Ithereby preventing .undue displace- Y of the two rail ends under the inliuence oifheavy, loads, but\permitting restricted .-lnii'fein'entin longitudinal direction due to chnges'-fo" temperature.

'"fiirth'er object of the invention aims at theprovision of a joint which consists of comparativeiyflevr parts of simple construct1J1 l l t,Wth theses/and other objects in View, whiclV-willfbecome apparent by reference toth'e" dr'r'wingand rthe specific:1tio1^r,tl1e pre'ferredffo1-fniof the invention consists in thenovel;'-arr'angernent and construction of i th'elparts;asg'fdescribed in the specification and fspeoiic'ally'pointed out in the appended In. the accompanying drawing, Figure l isia-'side lview 'ofthe vends of two rails to y which tlifej'ointin accordance with the inven- E'tioiifisapplied; "FigQ is a section on line -eAf 'of' Fig!" 1.51 Figl-' 3 is a section taken onlinelee'ofilig. "Fig. 4L is a perspective' vi'e'w j of sone :of Fi'gi''fisa perspective'fviewof one of the lower ilish plates,` l which simultaneously servesfasfamanti-creepingiieaiis. Fig. 6 is :ripersjfective' 'view-'of @clocking block to ,li'o'lfd the Lpartsinf' assembled po. ion.

'upper part of the fish plate lie' upper lish plates.`

the rails is equipped with a rectangular aperture at a suitable distance from the lend and close to the web for a purpose hereinafter indicated. A fish plate G, substan-l tially of rectangular form, is provided with extensions 7 which are adapted to enter the rectangular apertures of two adjoining railends. The middle portion of the lish plate 6 is thicker than the remaining part, whereby a rectangular' lug or projection S 1s formed. A similar plate 9 is placed directly above the plate 6 and represents the which overlaps both' rail ends. The plate 9 also has an enlarged middle portion 10 in the form of a rectangle which, however, projects beyond its lower edge, but originates somewhat below its upper edge. The middle portion 8 of the sh plate yo also originates slightly belowthe upper edge thereof, and its lower edge is substantially flush with the lower edge of the plate.k

The locking member l1 is of oblong forni and its lower part is forked, whereby prongs l12, 12 are formed between which a sliding block 13 is arranged to reciprocate in vertical direction, At the inside of the prongs l2 grooves 14- are provided adapted to receive lugs 15 of the sliding lock 13, whereby the latter is guided in its vertical movements. The sliding block 13 is formed at its lower end with an extension 1G oi.' suitable dimensions, and the locking member 11 is also formed with an integral extension 17 at its upper end adapted to enter the groove 3 of the rail head.` vln orderto join the two rail ends which, of course, are arranged in operative position, the iish plate' is arranged :is indicated in Fig. 1 so that its fiat face engages the Websof the rail ends, while its extensions 7 enter thercctangular apertures 5 provided in the rail fianges.' Thereupon the auxiliary fish plate i) is placed above the plate 6 in such manner that the portion 10Y thereof rests upon the upper edge ofthe plate G and upon portion S of the same, as will be readily understood by reference'to Fig. 2.

apertures the fish plates are assembled and automatically held in place. Subsequently the locking member 11 is applied in order to prevent the fish plates from leaving theirV operative position which would be the case when the rail ends are subjected to jars, vibrations. or the like. When locking the plates in position two locking members ll on each side of the rail ends are mounted so that the extension 17 also enters the groove 3 of the rail'heads and has a wedgelikc engagement with the upper tish plate il. During this operation the sliding block 12" is held in its upper or raised position until the locking melnber occupies operative position, whereupon the sliding block 1? is permitted to drop by its own gravity, whereupon the tongue 1G enters the aperture 5 and engages the extensionl Tof' the fish plate v (3. n

From the foregoing it is obvious that the v rail joint consists ot relatively few parts of simple and cheap construction which may be assembled andlocked in position without the employment of bolts, rivets, or theI like, and providing notwithstamlng this a highly eflieient and lasting rail joint which eti'ectively prevents the rails frontexecnting relative movements with respect to each other in vertical direction. Y

lt is apparent that the several parts of the rail joint may be altered and it is my intention not to bind myself specifically to the illustration shown by way of example, but, on the contrary, ant to avail myself ot' any departures which fairly fall within the scope ot my invention, as indicated in the appended claims.
